Thisoperates principally in the present instance on the lower or outer faceortion of the disk more than, or relative to, the upper portion of thedisk, where y the density of the disk in said portion is made to begreater than that in the portion of the disk above the same, so that thedisk tends to arch and its top surface is caused to assume intimatecontact with the top, wall of the shell and close any space orspacesthat might otherwise exist.v The shows how this arching in thepresent instance actually occurs (the top wall of the shell being bulgedupwardly slightly), said dotted line representing the curvature of theexposed face of the disk on a diameter thereof.

2. The method of forming a bottle-cap consists in placing a sealing diskin flatwise relation to a shell and then displacing the flange of theshell inwardly toward the-central or vertical axis of the shell fromdifferent radial directions simultaneously and forcing it into permanentoverlying relation to the margin of the disk, turning each portion ofsaid marginal part affected by such displacement lever-fashion about aline of bending coinciding with an annular line surrounding said axis,substantially as de scribed. .7

In testimony, that we claim the foregoing, we have hereunto set ourhands this 9th day of December. 1910.
